This present invention' relates to certainV new and useful improvementsina rail joint chair. V

The primary object of the invention resides in the provisionfof a railjoint chair which supports the rail on thepbottom of the flange as wellas under the ball of the rail.

The invention has for another object the provision of a rail joint chairof the character stated which provides ample bearing on theties, thuseliminating theuse of `tie plates under the rail joint chair.

The invention has for a further object the provision of a rail jointchair of the character stated which makes the joint as strong as therail, thus reducing the defiection when the wheels of the rolling stockpass over the joint.

The` invention has for a further object the provision of a rail jointchair of the character stated which provides a most substantial andfsmooth joint, eliminating the noise, and preventing the wear on the endof the rails. n

The invention has for a still further object the provision of a railjoint chair of the character stated which can be readily rolled in astandard rolling mill in long bars, sheared and punched in the flangethereof for spikes to provide a substantial fastening to the tieswithout requiring any expensive machine work.

The invention has 'for a still further object the provision of arailrjoint chair of the character stated which may be produced at smallcost, and sold at a popular price with good profit, thusproviding acommercially attractive proposition.

To the accomplishment of these and related objects as shall becomeapparent as the description proceeds, my invention resides in theconstruction, combination and arrangement of parts as shall behereinafter more fully described, illustrated in the accompany ingdrawings and pointed out in the claim hereunto appended.` j

The invention will be best understood and can be more clearly describedwhen reference is had to the drawings forming a part of this disclosure,wherein like characters indicate like parts throughout the severalviews.

'In the drawings f Figure 1 is a side elevation of the improved railjoint chair, showing the same in use; and Figure 2 is a transversevertical section therethrough, taken 'substantially' on the plane ofline 2 2 of Figure 1, looking/in the directionindicatedr by the arrows.

Referring more in detail to the drawings, it is to be noted that therail joint chair includes complementary members, each `of which has abase portion 6 adapted to fit under the rail base 7 and extendlongitudinally thereof. Each base portion 6 has an outwardly directedlongitudinal flange 8 through which spike openings 9 may be punched orotherwise provided for the' spikes 10 to beextended through and Adriveninto the t-ies 11 across which the complementary members are mounted.These ComplementaryV members are provided with grooves or corrugations6a on their under faces and are also adapted to rest in `depressions orpockets 12 provided therefor in the upper face of the ties 11 so as toprevent spreading of the rail. To compensate for this inclining of thecomplementary members7 they have their base portions 6 bevelled on theirupper faces so as to support the rail base 7 in proper horizontal planethereon. If desired, the

- grooves or corrugations 6a or the depressions or'pockets 12, or both,may be dispensed with and the complementary members 6 mountedy inupright position on the ties 11. The complementary members are employedat a rail joint and the body portions 13 of said members rising from'theflanges 8 thereof and eX- tending upwardly toward one another inslightly inclined planes-are adapted to ex" tend overV the upper face ofthe rail base 7 of the opposed rail ends forming the rail joint and saidbody portions 13 of the complementary members normally rest upon andbind on the upper face of the rail base'7, at the inner longitudinaledges 14 of saidv body portions 13 of the complementary members and nearthe connection of the longitudinal inner edges of the rail base 7 withthe upstanding rail web 15. The upstanding or fish plate portions 16 ofthe complementary members rise from the body portions 13 ioo thereof soas to have their inner faces normally spaced from the opposite faces ofthe rail web 15. The upper edges 17 of the complementary members arebevelled or inclined outwardly so as to rmly engage the bevelled underfaces 18 of the rail head or tread 19. The upper edges /17 of theupstanding portions 16-.of the complementary members Vbind against andat all times firmly contact with the under faces 18 of the rail head ortread 19. It is also to be 'noted that bolt openings'` 20 are providedin the upstanding portions 16 of the complementary members registeringwith corresponding bolt openings 21 Vin the rail web 15 to receive thebolts 22 extended through said web 15 of the rail and through theupstandinig portions 16 of the complementary members, with lock nuts 23or thev like carried on the threaded ends of the bolts 22. Attention maybe also directed at this time tothe main part of the base vportions 6"of the complementary -members binding againstithe underface. of the-raihbase 7 gat all times. Likewise, Yitis to .be noted thatl theopposed edges ofthe -baseaportions 16 of the complementary members arevnormally spacedv vapart beneath the centre of theV -rail y g base 7 andspaces are also provided betweenl chair is subjected to exceptionalstrain and atl the other pointsthe parts are normally the outerlongitudinal edges of ythe rai-l; base 7 and the Aupstanding inner wallsbetween the 'base portions 6 yand the body portions 13 of said.complementary "members, thus permitting inward movement of saidVcomple-- mentary members lon the opposite sides of f the rail sections,if required, for an adjustmentY of saidV complementary members and saidArail sections.

As the construction ofl the device lhas .-.thiis been described indetail, vbrief reference is now had to its use and Vmodus operandi z.

The rail ends are effectively and firmly held in the proper horizontalplane and outwardV spreading of* thev rail sections is prevented.Furthermore, the rail endV sections are firmlyl i held between andrclamped by the complef mentary members constituting the rail. jointseparated, thuspermitting sufficient eXpansion and contraction of theparts, to assure the highest efficiency of results and automaticadjustment or regulation of they Various parts, with respect to oneanother. When required, the lock nuts 23 `may be readjusted on thezbolts22, to bring the complementary the rails, at the joints thereof ispreventedv by this improved rail joint chair.

From the foregoing. description taken in,

connection withv the accompanying drawings, it will be manifest that arail joint chair is provided that will fulfill all the necessaryrequirements olf such adevic'e but as many changes could be made in theabove description and -many apparently widely?- different embodiments ofmy invention' may be constructed within the scope ofthe appended claimywithout departing from the spirit or scope thereof, it is intended thatall matters contained in the said accompanying specification anddrawings, shalll be interpreted. as illustrative and not in `a` limitedsense.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is A rail joint chair including the combinationwith the opposed ends of rail sections and Across ties beneath thelysame providedadjacent their ends with inclined pockets in their upperfaces having upstanding outer end walls; of a `pair of complementaryrail joint chair members having basexportionsV with their under facesbeveled transversely and serrated for engagement with the bottom wall ofsaid pockets in saidy cross ties; the outer chair member engagingagainst the upstanding outer endv wall of said. pocket to preventoutward movement of said 'complementary rail joint chair memberson saidvties; said complementary rail joint chair members having recessesintheir base vp0rtioiis to receive the base portions of said. railsectionoends Awith'ftlie baseportions of said complementary rail jointchair members binding on the underface and the upper face of said baseportions of the rail section ends said complementary rail joint chairsections having upstanding portions opposite the web portions of saidvrail section. ends with the upper edges of said upstanding portions ofthe complementary rail joint chair members bearing against theunder-face of the tread portions of said rail section ends; means forfirmly retaining the upstanding portions of said complementary railjoint chair members in position on opposite sides of said yrail sectionends; and means for rmly retaining i said base portions of thecomplementary rail joint chair member on'said ties. f

In testimony whereof I hereunto signature.'
